Here are the classes:

How do I create a button that will show the second activity?

I was trying to open an Activity of an other applicatoin by using an implicit Intent. It doesn't work, I thought it is possible to start an Activity of an other Application by using implicit Intent. Or do I missunderstand it?
I added following intent-filter to the AndroidManifest of Application A:
CODE:..............
And called the Intent in Application B by using folloing code:
CODE:.............
All I get ist, the error message that Application A was stoped unexpectedly.
I am interested in activating another application's activity. I know from reading the Android SDK that it's probably better to do this with an implicit intent. However, this activity doesn't reside in an application I own, so I don't know the action and category and data flags on the intent-filter.
How can I examine an Android applications metadata like the activity classes and the intent-filters for those activities (if declared in the manifest)?
Can we show the dialog when our application/activity startup?
View 4 Replies View RelatedI have an application that I have running a media player and I want to resume the activity from my applications home activity. I can successfully do this by adding the following flags to the startActivity Call:
myIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
I am worried that this is not an ideal way to do things since it took me a long time to find it. It made me think that no one uses it very much. Are there any pitfalls to using this method?
My app works with pictures. It can take multiple pictures as an input, process them, and send them again to another app.
As a consequence, my main Activity has declared an intent filter on ACTION_SEND_MULTIPLE for image/* mimetypes and can result in issuing a new Intent with the same action and data type using Activity.startActivity(Intent).
Is there a way to exclude my own activity from the list of apps that is displayed to the user after the startActivity() call ?
I have found this erroneous behaviour on my phone, please let me know if you have any idea how to resolve it. However, when I open this intent, the gps on the device starts and google maps first displays my location instead of the location in the URI. This happens only the first time you open google maps. If I go back to my app and make the same selection, then the correct position on the map appears.I tried using something like this: geo:0,0?q=*business+near+city, however this doesnt centers the map on a position, but in the nearest address.
View 2 Replies View RelatedI have looked at the intent-filter documentation and I can't figure out this specific intent-filter. I'm looking to use ACTION_SEND because I only want the app to show up in "Share" menus in other apps. I only want to show up in the share menu if the text of the intent is a url. For example, what is shared from the Android Browser's share menu. I don't want the app to appear in the share menu if it's just text and not a url.
View 1 Replies View RelatedI'm having difficulties handling multiple instances of my root (main) activity for my application. My app in question has an intent filter in place to launch my application when opening an email attatchment from the "Email" app. My problem is if I launch my application first through the the android applications screen and then launch my application via opening the Email attachment it creates two instances of my root activity. steps: Launch root activity A, press home Open email attachment, intent filter triggers launches root activity A Is it possible when opening the Email attachment that when the OS tries to launch my application it detects there is already an instance of it running and use that or remove/clear that instance?

View 2 Replies View RelatedI'm switching between different Activities using Intents. For one Activity, I would like it to clear the history stack so when the user presses the back button, it takes them Home instead of previous activities in my application.
View 2 Replies View RelatedI've searched for a few hours for a solution to this, so hopefully this isn't a repost I'm setting a shortcut on the Home screen which raises an Intent to my application - the problem is that I don't want to show my app, just run a little code and display a Toast notification. This must be possible - I just can't work out how.. Once I'm handling the shortcut Intent in onCreate() the UI has initialised and I get a little screen flicker if I then run my code and finish().
View 4 Replies View RelatedI have a service that is downloading a file. When the download is done, I would like to update my "Downloaded files" list in my Activity, but only if the Activity is running. I do not want the Activity to start if it's not already running. I was hoping I could do this by making a new Intent with some special flag. Anyone have any idea how I can achieve this? A tiny code example maybe?

View 1 Replies View RelatedI'm having a struggle understanding why my intent is not working. I basically just copied paste from other examples in my code that work perfectly like this. Here it is:
Intent addIntent = new Intent(v.getContext(), thenNnowMode.class);
Bundle w = new Bundle(); String activityName = "addPic";
w.putString("activity", activityName);
w.putParcelable("bitmap", selectedDeviceImage);
//a.putString("id", picId); addIntent.putExtras(w);
startActivity(addIntent); finish();
The intent is opening a different class called thenNnow.class instead of thenNnowMode.class and I have no idea why this is happening. I've tried sending the intent to open other activities other than thenNnowMode but it always opens thenNnow. Am I missing some silly syntax mistake? It's so strange, its the same code. I am not sure if it's relevant but the thenNnowMode class uses the device camera
My program has a list of tabs that each contain a list of people.Clicking a person should edit their details, but instead, clicking a person throws an ActivityNotFoundException.
View 2 Replies View RelatedI've got two activities, one of them is called MyActivity. I want both of them to be able to use a function located in a class othat we may call MyClass. In MyClass, I try to use an intent to launch the activity AnotherActivity. Since the constructor takes a context as parameter, I simply tried to store a context from the activity in the constructor, and then use it when I try to create my intent.However, even thought none of the arguments are null (checked that with a simple if-statement), intent seems to be null and a NullPointerException is thrown. Why does it not work, and what can I do to solve the problem?
I'm quite new to Android and Java development, so please explain it as basic as you can.
I want to create 4(four) tab, on click of each tab i need to call some activity through Intent, upto this is OK, but without replacement of whole page, I would not like to replace tab, tab will remain (unchanged) same for each a every layout/activity, i.e, only lower part (content) parts will change.

But obviously that isn't legal so how could I structure an expression to check from what class an intent was started.
